Watch: Sharks found in underwater volcano

Using a deep-sea camera, scientists have filmed sharks swimming in the crater of an underwater volcano near the Solomon Islands, National Geographic reports. Because little is known about the geology and biology of the volcano, called Kavachi, the researchers dropped the camera and other instruments into the water for a better look. Caught in their footage were hammerheads and silky sharks, seemingly undisturbed by the water’s acidity and hot temperature. The discovery raises questions about what extreme environments the sharks can endure and how, the scientists say.
